title: On the existence of a structural instability in sub-critical crystalline fluctuations in a supercooled liquid.
abstract: The square gradient free energy functional is used to describe the distribution of sub-critical crystalline fluctuations in a supercooled liquid. We show that for any supercooling there exists a cluster radius of 3-4 particle diameters below which the crystalline order is no longer stable. We explore the consequences of this observation.
